Development and utilization of laser-ion beam photodissociation
(1985)
Laser induced photodissociation of fast (3-8 keV) ion beams has been developed for use in both a coaxial and perpendicular beam arrangement. The laser-ion beam photodissociation technique has been used as a probe for ...
Molecular and electronic structures of some chiral complexes of dimolybdenum (II)
(1985)
The complexes β-Mo2X4(PP)2; X = Cl, Br; PP = S,S-dppb, dppe, dedp have been synthesized starting from Mo2(O2CCF3)4 by using Me3SiX; X = Cl, Br, as reagents. A synthetic route has been found which yields mixed ligand complexes ...
Ion induced microscopic mass spectrometry
(1985)
A microprobe analytical technique has been developed. It is based on mass spectrometric analysis of the ions desorbed from the impact area of a collimated microbeam of high energy heavy projectiles (84 MeV ^84Kr^+7). This ...
Microlocalization during ion beam analysis
(1985)
We have investigated three techniques for identifying microregions of the sample examined by an ion beam during analysis. These techniques involve 1) the detection of secondary electrons ejected from the sample during ion ...
A study of qualitative and quantitative aspects of particle desorption mass spectrometry
(1987)
The goal of this study has been to expand the analytical scope of ²⁵²Cf particle desorption mass spectrometry (PDMS). The technique has a unique set of features: simple spectra, usually with a predominant parent ion peak ...
Kinetic studies of pyridoxal and pyridoxal-metal ion catalyzed dealdolation of novel [beta]-hydroxy amino acid model systems
(1979)
The rates of dealdolation of pyridoxal and pyridoxal-metal ion catalyzed [beta]-hydroxy amino acid model systems have been determined by proton nmr. The reaction rate is enhanced by the presence of electron donating groups ...
Separation and equilibrium characterization of two diastereomeric multidentate ligand pairs for use as radiopharmaceuticals
(1989)
The multidentate ligand N,N'-ethylenebis[2-(o-hydroxyphenyl)- glycine] (EHPG) contains a mixture of racemic and meso forms of the ligand. Theoretical work has addressed the differences in the stabilities of the meso and ...
Enzymes in organic synthesis
(1988)
Immobilized glucose dehydrogenase from Bacillus sp. was found to be a practical catalyst for NAD (P) H regeneration. It is very stable at high temperatures. Coupled with an appropriate alcohol dehydrogenase, several compounds ...
The purification and characterization of the phosphotriesterase from Pseudomonas diminuta
(1989)
The phosphotriesterase from the soil bacterium Pseudomonas diminuta has been purified to homogeneity from two different expression systems using only three chromatographic steps. This represents the first total purification ...
